If you repeatedly switch on seat heating, the
seat cushion and backrest padding may
become very hot. The health of vehicle occu-
pants with limited temperature sensitivity or a limited ability to react to excessively high
temperatures may be affected or they may
even suffer burn-like injuries. There is a risk of
injury.
Therefore, do not switch on the seat heating
repeatedly. Driver's and front-passenger seat

Problems with the seat heating The seat heating has switched off prema-
turely or cannot be switched on. The vehicle's
electrical system voltage is too low because
too many electrical consumers are switched
on.
X Switch off electrical consumers that you do
not need, such as the rear window heating
or interior lighting.
X Once the battery is sufficiently charged,
switch the seat heating on again. Seats
